  • Fix: IWRegion reduces the height in the first async call;
  • Fix: IWRegion can be resized to a size greater than its original size;
  • Fix: IWRegion borders are not rendered correctly in async calls;
  • Fix: GIF images not supported on D2007
  • Interface section of several IntraWeb units are now included in the installer (check folder "Interfaces")


  • Master templates were not being merged in D2009 and higher
  • IW applications hangs when running on Chrome


  • Changes to accommodate the new changes in UTF8ContentParser by CogeGear, that fixes the Chinese Characters bug


  • IW DB Controls: Changes made to a Dataset within async calls were not updating the IW DB Controls tied to this Dataset
  • TIWFile: More fixes for the Range Check Error
  • TIWFile: When an IWFile is present on the form, any IWButtonClick will reset IWEdits fields and IWCombos selected items
  • TIWFile: Revert changes that broke file transfer (file is corrupted after transfer)


  • TIWFile: Fix for the Range Check Error bug;
  • TIWFile: Changes to speed up the file processing at the server side (Thanks to Pete d'Oronzio).


  • Fixes the mismatch unit problem after D2009 updates #3 and #4 and also the "Unit InIOHandler was compiled with a different version of InGlobal.ValidEncoding" error, which appeared for some users.


  • Fix reverted: Application fails with a Session Timeout when the URL in TIWURL.URL does not contain a https:// in the url address. Same applies for TIWFileReference (ServerController.SessionTimeoutURL.URL). This fix caused 'https://' to be included in relative URLs


  • Installer: IW components are now visible in the pallete in C++Builder 2007 and C++Builder 2009
  • Installer: a missing directive prevented recompilation of TMS packages with IW 10 in CDS 2009
  • Installer: added missing HPP files
  • Fix: every character adds an extra space and just half of the line is added to the log/err file in CDS 2009
  • Fix: IWRegion Resizing/Async events: A simple ASYNC call to show/hide a IWRegion cause it's size to change (by modifying it's border width), reducing the width of the IWRegion
  • Fix: Application fails with a Session Timeout when the URL in TIWURL.URL does not contain a https:// in the url address. Same applies for TIWFileReference (ServerController.SessionTimeoutURL.URL)
